HARTFORD, Conn. — The average price of a gallon of regular self-serve gasoline in Connecticut has jumped above $4 this weekend.

That’s according to Saturday’s survey from auto club AAA, the Oil Price Information Service and Wright Express. It shows the price rose to $4.003 overnight, from $3.999 on Friday.

The last time the average price went above $4 was May 16 of this year. The highest average of $4.39 per gallon was recorded on July 9, 2008.

Connecticut motorists are now paying more than they were a year ago, when the statewide average price for gasoline was $3.91. Problems with refineries and pipelines elsewhere in the country helped push gasoline prices higher over the last several weeks.
